The Racah algebra and superintegrable models (1312.3874v1)
Published 13 Dec 2013 in math-ph and math.MP
Abstract: The universal character of the Racah algebra will be illustrated by showing that it is at the center of the relations between the Racah polynomials, the recoupling of three su(1,1) representations and the symmetries of the generic second-order superintegrable model on the 2-sphere.
